PI CKLING APPARATUS Filed March 22, 1929 5 Sheets-Sheet 3 INVENTEIR sfephe n L.Wi//iams ATTDRNEY Patented Dec. 3, 1929 UNITED STATES PATENT OFFICE STEPHEN L. WILLIAMS, OF BBIDGEPORT, OHIO, ASSIGNOR TO EX'IBUIDED METAL PRODUCTS COMPANY, OF BRIDGEPORT, OHIO, A CORPORATION OF OHIO PICKLING APPARATUS Application filed. March 22, 1929. Serial No. 349,067.

This invention relates to pickling apparatus and more particularly to an apparatus for use in the pickling of coils of wire and the like.

The primary object of the invention is to provide an apparatus foreffecting thorough and expeditious pickling of the wire, and more specifically to impart a bodily movement to the coils of wire in a curved path in the pickling fluid.

A further object of the invention is to provide a pickling apparatus in which means is provided for opening or spreading the convolutions of the coils of wire during the bodily movement of the coils in a curved path, thereby to expose the entire circumfer- %nce of the wire to the action of the pickling uid.

lin describing the invention in detail, reference is herein had to the accompanying drawings, in which- Fig. 1 is a top plan view of the invention; gig. 2 is a section on the line 2-2 of Fig. 1; an

Fig. 3 is a section on the line 3-'-3 of Fig. 2. As shown in said drawings, a pair of tanks 1 are employed for containing the pickling fluid, such tanks being mounted in parallel relation. A pair of supporting columns 2 are disposed in spaced relation and to one of the ends of the tanks 1, while a similar pair of spaced supporting columns 3 are located adjacent to the opposite ends of the tanks 1. The columns 2 are connected by a horizontal girder 4 and a similar horizontal girder 5 connects the columns 3. V

A horizontal shaft 6 is carried in a bearing supported by the girder 4 and a similar horizontal shaft 7 is carried in a bearing sup ported by the girder 5. Radial arms 8 are affixed to the shafts 6 and 7 and extend horizontally towards one another. These arms, as shown particularly in Fig. 1, have bifurcated free ends 9, to which latter yokes 10 are pivoted, said yokes serving to support the wire coil carrier.- The carrier is composed of a horizontal bar 11 the ends of which rest in and on the closed bottoms of the yokes 10. The bar 11 is provided adjacent to its ends with depending members 12 and 13,

the member 12 being pivoted at 14 to bar 11 and is of substantially U shape. A horizontal member 15 is pivoted at 16 to the member 13 and has its opposite end free and formed to rest upon the closed bottom of the U shaped member 12. The pivoted end of the member 13 is shouldered at 17 and en gages a corresponding shoulder formed on the bottom of the member 13, thereby to hold the member 15 rigidly in position by the weight of the wire coils G, as shown in Fi 3. Preferably the upper face member 15 is of undulating formation so as to provide seats to receive the inner circumferences of the wire coils to hold the latter against shifting longitudinally the member 15. The bar 11 is provided with an eye or loop 18 for engagement with a lifting crane, as will be later set forth.

In order to effect oscillatory movementsof the shafts 6 and 7, the shaft 6 is provided with a depending arm 19 to which is pivoted at 20 one end of a long link 21, the opposite end of the link being connected to an eccentric 22 mounted on a shaft 23. The shaft 23 is driven by an electric motor M which is connected thereto and together with the shaft is mounted on a base 24. The shaft 7 is provided with a similar depending arm 25 to which is pivoted at 26 a short link 27 the latter link being connected to a similar eccentric 28 mounted on the shaft 23, whereby it will be seen that upon operation of the motor M each of the shafts 6 and 7 will be given synchronous oscillatory movement thereby causing the arms 8 to vertically reciprocate and to cause corresponding movement of the wire coil carrier.

- A cradle 29 is provided and is stationarily 'held within the tank, the cradle having spaced longitudinal bars 30 which latter are disposed in the arc of a circle. Clamping brackets or clips 31 are secured to the top edges of the sides of the tanks and are provided with downwardly and convergently related rods 32 which latter are secured at their lower ends to the cradle 29 whereby the cradle is stationarily supported in the pickling tank.

In operation, it will be seen that in order to load the coils on the carrier the carrier is disconnected from the apparatus, the free end of the member is first raised and the member 12 is then swung outwardly or to the left of Fig. 2, which enables the coils to be moved onto the member 15 or the wire coils to be threaded on said member. After this positioning of the coils upon the member 15, said member is moved to the position of Fig. 2, in which position it engages the member 12. A lifting crane is then connected to the carrier by means of the eye 18 thereof and is then moved to position and lower the carrier to cause'its bar 11 to be disposed in the yokes 10 and engaged with the bottoms thereof. Power is then applied to the shafts 6 and 7 thereby to cause same to oscillate, effecting vertical reciprocal movements of the yokes 10 and therethrough of the carrier.

Referring particularly to Fig. 3 of the drawings, it Will be seen that the bar 15 of the carrier which projects through the centers of the coils C, is located to one side of or out of vertical alinement with respect to the center of the are on which the cradle is struck.

. Consequently there is an ofi'center relation between the bar 15 and the curvature of the carrier, therefore, as the carrier reciprocates vertically the wire coil G will be impacted against the cradle, thus imparting a simultaneous rolling movement of the wire coils C and spreading or opening up of the convolutions of the coils, which enables the pickling fluid to have free and complete access to the entire circumference of the wire.

It is, of course, to be understood that the number of the tanks can be increased or decreased as desired and that other changes and modifications may be resorted to within the scope of the following claims.

By the use of a stationary cradle as distinguished from my copending application here with filed, March 22, 1929, Ser. No. 349,066, I am able to employ a cheaper or more economical apparatus and to operate same with less power, although the diameter of the coils which can be pickled in accordance with the present invention are less than in the instance -of my said copending application in which coils of greater and difiterent diameters can be employed due to the fact that both the cradle and the wire carrier reciprocate.

What is claimed is v 1. In a pickling apparatus, a pickling tank, a pair of shafts at the upper part and adjacent to the ends of the tank, a radial arm carried by each shaft, a wire coil carrier secured to the arms, a cradle within the tank, disposed withits axis to one side of the axis of the carrier, means to rigidly mount the cradle, and operating means for the shafts, said cradle having a curved portion to engage the wire coilas the latter moves downwardly so as to impart a rolling movement to the coil and to cause the convolutions of the coil to spread by impact against the cradle.

2. In a Wire coil pickling apparatus, a pickling tank, a stationary cradle in the tank, a wire coil carrier disposed to have its axis to one side of the axis of the cradle, and means to effect approaching and receding movements of the carrier relative to the cradle whereby to cause the coils to be impacted against the cradle and their convolutions thereby spread, said cradle having a curved portion so as to also impart a rolling movement to the coils.

3. In a wire coil pickling apparatus, a pickling tank, a wire coil carrier, means to impart vertical reciprocatory movement to the carrier, and stationary means in the tank having a curved part to engage the coils and to impart a rolling movement thereto.

5. In an apparatus for pickling wire coils, a pickling tank, carrier means for the wire coils adapted to extend through the open centers thereof so as to enable the coils to rotate relative to the carrier means, means to vertically reciprocate the carrier, and curved stationary means in the tank to engage the coils so as to cause spreading of the convolutions thereof and to simultaneously cause rolling of the coils.

6. In a pickling apparatus, a pickling tank, a wire coil carrier means, means in the tank having a downwardly inclined part, and means to move one of the last two named means in a plane fixed relative to the tank and toward and away from the other to effect bodily rotation of the coils.
